COINCONTBOLLED VENDING-MACHINE.

Specincation of Letters Patent.

Patented July 3o, 1912.

Application led April 27, 1911. Serial No. 623,620.

.specilcation Similar characters refer to similar part-s in the several ligures therein.

Figure 1 of the drawings is a view in front elevation of a coin-controlled vendingmachine containing my invention. Fig. 2 is a'vertical crosssection of the same taken just inside the end wall of the case of the machine. Fig. 3 is a view on an enlarged scale of the` coin-holder and `the coin-operated mechanism, showing the same in side elevation. Fig. 4 is a horizontal cross-seci tion taken on the broken line 4-4 in Fig.

2, showing in top plan the operating mechanism which appears in Fig. 3. 4Fig. 5 is a vertical cross-section taken on the broken` line 5-5 in Fig. 3, showing a front elevat-ion of the coin-holder. i

The operating mechanism ofmy improvedmachine is adapted for the delivery of Iner-` chandise of various kinds; and I have shown in the drawings my invention a plied to a machine vmore particularly adhpted -for vending golf-balls or the like. v

Referrlng to the drawings wherein the invention is showny in preferred form, 1, is a movable rack having a series of pockets, 2, each adapted to receive a golf-ball, and each opening on th 'front side whereat the pockets are adapted to successively register with an aperture, 3, in the front wall of thecase as the machine is from time to time operated. As each pocket, 2, is brou ht o posite theaperture, 3, the ball is re ease from said pocket and can be delivered out through said aperture. The rack, 1, is supported 1n an elevated position by means of a chain, 4,

which passes over pulleys, 5 and 6, and is connected with a drum, 7, upon which the chain is wound. The weight of the rack is sufficient to cause itto descend when the drum is left free to rotate.

Normally the drum, is held against` rotative movement by the, engagement of stops, 10, on the drum with' stops, 11, on the ends ofthe respective coin-actuated levers, 13 and 14, both pivotally niounted upon a crossrod, 15, and' normally held in engagement withthe ydrum-by means of the respective coil-springs, 16. Anescapement lever, 17,

fulcrumed at, 18, also has a stop, 19, which is normally held in the path of stops, 9, on the drum by'means of a coil-spring, 20.

A movablecoin-carrier, 21, is located beneath a pair of coin-chutes, 2,2 and 23, in position to receive therefrom in pockets, 24 and 25, coins, 26 and 27, of diiierent values. The coin-carrier is held retracted "by means of the coil-spring, 28, and is adapted to be moved toward the levers,13, 14 and 1 7, by means of a crank-handle, 29, on one of the trunnions whereby the coin-carrier is rotatively mounted. The coin-carrier has in the back wall of each pocket, 24 and 25, a slot 30, adapted to receive the respective levers, 13 and 14, without engaging the same, should the coin-carrier be operated when there is no coin therein. The pockets, 24 and 25, are adapted to support the respective coins across the respectiveslots, 30, and

vin position to engage therespective levers,

13 and 14, when the coin-carrier is actuated by the crank-handle. A y

lTo operate the machine as shown, it is necessary to insert two coins ofv proper denomination in the respective chutes, 22 and 23. When these cpins have entered the respective pockets, 24|and-25, the crank-handle, 29', is turned to bring the coins into engagement with the respective levers, 13 and 14, and the continued movement of `the crank-handle will cause said coins to operate said levers until their stops are moved out of the path "of the stops, 10, on the drum permitting the drum to respond to the pull of the chain, 4, and to partially rotate until the stop, 19, on the escapement lever, 17, is engaged by the next stop, 9, in rear thereof on the drum. A. further movement of the hand,

crank,f29, causes the coins to pass beneath and past the engaged ends of the levers, 13 and 14; and as the coin-carrier becomes more inclined, the coins-fall therefrom into a cash-drawer, 32, placed to receive them.

The final movement of the .coin-carrier, 21,

which thus deposits 'the coins in the cashdra'wer brings into engagement with the endof the' lever, 17, an unslottedor solid portion of the coin-carrier whereby said lever isoperated to cause its stop, 19, to be raised out of the path of the pin, 9, with which it is in engagement. Meanwhile, the levers, 13 and 14, have been released from engagement with the coins and have resumed their normal position with their stops, 11, in the path of the stops, 10, on the drum. It will thus be seen that eachl full inward movement of the coin-carrier, 21, will permit the drum to partake of approximately one-half of a complete rotation, the operation of the levers, 13 and 14,'1removing the stops, 11, from engagement with; one set of stops, 10, on the drum whereby the drum is permitted to partially rotate until the next rearwardly located stop, 9, on the 'drum enga es the stop, 19, on the lever, 17; and when t e lever, 17, is operated to release the stop, 9, a further partial rotative movement of the drum is permitted until the next rearwardly located set of stops, 10, engagesthe stops, 11, on the levers, 13 and 14, which have meanwhile resumed their nor al positions. The diameter of the drum, 17, is such that a half rotation thereof -will permit the rack, 1, to descend a distance equal to the height of one of the pockets, 2. 1

The machine shown and described is particularly adaptedfor vending golf-balls at a price of seventy-five cents; the coin-chutes belngadapted to receive half-dollars and quarter-dollars respectively.

For vending f merchandise the price of which can be represented by a single coin, one of thelevers, 13 and 14, with its corresponding coin-chute can be omitted. Whenv it is desired rto elevate the rack, 1, the-chain, 4,1can be wound upon-,the drum, 7, by rotating the drum| in the pro r direction by means of a vkey or wrenc applied to the angular, end, 36, of the drum-trunnion, the several stops being beveled to permit them to ride past one another when the drumris rotated in the direction last reerred to. f A spring, 35, engagesa toothed rack, 39, on the back of the rack, 1, serving to steady the. rack and prevent an unintentional upward movement thereof.

During vthe winding up of the drum, 7, as .above described,lthe spring, 35, is held out of engagement with the toothed rack, 39, by

said spring having an arm, 40, projecting through an aperture, 41, inthe endwall of the case forthat purpose.Y

What I claim as new and desire-to secure by Letters Patent is- 1. In a machine of the classdescribed, and 1n means tending to rotate pair of levers; stops on and drum Iadapted to permit an escapement movement of the drum` when said levers are successively operated; a coin-carrier by movement of Iwhich said levers are successively actuated, saidcarrier havingmeans for supporting a coin in positiontoengage the first actuated lever; and external means for operating said coin-carrier.

2. In a machine of the in combination, a movable coin-,carrier having a coin-pocket provided with an lopening in the wall thereof; external means for moving said coin-carrier; a coin-chute leading to said pocket; a rotatively mounted drum; means tending to rotate said drum; a lever pivotally mounted opposite said pocket and .adapted to play through the opening in the wall thereof and adapted to be enga ed by a coin located in said pocket during tilde imtial movement of said carrier, and to automatically release said coin before the iinal movement of said carrier; an' escapement lever mounted in the path of said coin-carrier and adapted to be operated by the final movement thereof; tive levers and drum to permit an escapement movement of the drum as said levers are successively operated. f
